Product overview
Nicfa Airflow Ultra is a compact, fully automated laminar flow and filtration system engineered for critical ISO5 operating rooms. It integrates AISI304 stainless steel construction, H14 absolute filtration, continuous environmental monitoring via the Nicfa Smart System, and design features that simplify installation, cleaning and maintenance.

Key features

• Compact mixing chamber with total thickness 350 mm for installation in false ceilings and constrained ceiling spaces.
• Mixing chamber in AISI304 stainless steel with four-side power supply possibility; internal compression grid for structural stability and filter retention.
• H14 absolute filters (68 mm) with aluminium frames, mounted horizontally in a stainless steel containment grid for tool-free insertion; filters cover up to 92% of the ceiling surface.
• Double gasket and double sealing grid system to prevent leakage or bypass of unfiltered air.
• Motorized independent containment grids with synchronized intelligent compression (automatic filter locking) controlled by the Nicfa Controller or external systems, enabling uniform sealing without manual intervention.
• Integrated tilting mechanism for safe access to the mixing chamber to facilitate cleaning and sanitization operations.
• Micro-perforated Acotex technical fabric panels to distribute sterile air uniformly; available with uniform or differentiated mesh to fine-tune laminar flow.
• Panels divided into removable sections to accelerate daily maintenance (quick removal, cleaning and reinstallation).

Nicfa Smart System (environmental monitoring and intelligence)
The Nicfa Smart System continuously monitors critical environmental parameters, interprets them in real time and adapts laminar flow, filtration and sanitization devices to maintain ISO 14644 compliance. It provides detection, automation, traceability and tools for control, interaction and strategic analysis.

Monitored parameters

• Room and flow temperature
• Humidity
• Pressure differential
• Flow velocity
• Flow rate values
• Particulate contamination

Smart System functionalities

• Anomaly detection with immediate reporting on the graphical interface for rapid intervention.
• Notifications and alarms for malfunctions or emergency situations, sent to on-site and remote technical staff.
• Communication and integration with Building Management Systems (BMS) for continuous information exchange.
• Data logging: all monitored parameters are stored for analysis, performance evaluation and regulatory compliance, with options for local, cloud or hospital server storage.
• Remote access for technicians to provide support, adjust settings and perform interventions.
• Digital environmental dossier: integration with reporting systems to document and make environmental condition records traceable and available.
• Nicfa Eyes: monitors the critical area under the laminar flow and automatically activates the AHU when motion is detected; switches to ECO mode when no activity is present to optimize consumption.

Expandable recirculation unit (optional)
Airflow Ultra can be equipped with an integrated recirculation unit to increase operating efficiency, autonomy and internal climate control without significant energy penalty. The recirculation unit is constructed in AISI304 stainless steel with a technopolymer finish and can be installed remotely on two sides of the mixing chamber.

• Each module integrates 2 single-suction centrifugal fans, direct drive, with high-performance impellers.
• GreenTech EC motors with external rotor, integrated electronic control, efficiency exceeding IE4 class, maintenance-free; motor power up to 0.75 kW and flow rate up to 1500 m³/h.
• Four integrated silencers (two on suction side and two on delivery side) for very low noise operation.
• Complete management by the Nicfa Controller and dynamic regulation by Nicfa Probes to adjust airflow based on actual environmental conditions.

Compliance, efficiency and manufacturing
Nicfa Airflow Ultra is engineered for continuous technical performance, safety and regulatory compliance. The system integrates high-efficiency components and automatic regulation to optimise energy use according to actual room activity. Manufactured in Italy, the product can be customised to project specifications to meet clinical and regulatory requirements.
